Answer:

[tex]\boxed {\boxed {\sf 3 \ pounds \ of \$4 \ candy}}[/tex]

[tex]\boxed {\boxed {\sf 2.5 \ pounds \ of \$3.50 \ candy}}[/tex]

Step-by-step explanation:

Let's create a system of equation. First, define the variables. One type of candy is x and the other is y.

Now, create 2 equations, one for the weight and one for the price.

[tex]x+y=5.5[/tex]

[tex]4x+3.5y=20.75[/tex]

The first equation represents the mixture of both types of candy that weighs 5.5 pounds. The second represents the prices of the candy and the mixture.

Next. solve for the variables using substitution. Isolate a variable in the first equation. Let's isolate y by subtracting x.

[tex]x-x+y=5.5-x\\y= 5.5-x[/tex]

Now, we know what y is equal to, so we can substitute it into the second equation.

[tex]4x+ 3.5 (5.5-x)= 20.75[/tex]

Distribute the 3.5. Multiply each term by 3.5

[tex]4x+(3.5*5.5)+(3.5*-x)[/tex]

[tex]4x+19.25-3.5x= 20.75[/tex]

Combine like terms on the right side.

[tex]0.5x+19.25=20.75[/tex]

Subtract 19.25 from both sides of the equation to isolate the variable.

[tex]0.5x+19.25-19.25=20.75-19.25[/tex]

[tex]0.5x= 1.5[/tex]

Divide both sides by 0.5.

[tex]\frac {0.5x}{0.5}= \frac{1.5}{0.5}\\x=3[/tex]

Now we can substitute x back into the first equation and solve for y.

[tex]x+y=5.5\\3+y=5.5[/tex]

Subtract 3 from both sides to isolate the variable.

[tex]3-3+y=5.5-3\\y=2.5[/tex]

There was 3 pounds of the $4 candy and 2.5 pounds of the $3.50 candy.

Step-by-step explanation:

180-90-51=39

Answer:

its 39

Step-by-step explanation:

you know that a right triangle already has the angle 90 so 51 plus 90 equals 141

180-141=39

i wont give the answer but i will tell you how to solve

Opening Exercise

The original triangle, labeled A, has been reflected across the first line, resulting in the image labeled B. Reflect the image across the second line. Carlos looked at the image of the reflection across the second line and said, “That’s not the image of triangle A after two reflections; that’s the image of triangle A after a rotation!” Do you agree? Why or why not?

Discussion

When you reflect a figure across a line, the original figure and its image share a line of symmetry, which we have called the line of reflection. When you reflect a figure across a line and then reflect the image across a line that intersects the first line, your final image is a rotation of the original figure. The center of rotation is the point at which the two lines of reflection intersect. The angle of rotation is determined by connecting the center of rotation to a pair of corresponding vertices on the original figure and the final image. The figure above is a 210° rotation (or 150° clockwise rotation).

Exploratory Challenge

Line of symmetry of a figure: This is an isosceles triangle. By definition, an isosceles triangle has at least two congruent sides. A line of symmetry of the triangle can be drawn from the top vertex to the midpoint of the base, decomposing the original triangle into two congruent right triangles. This line of symmetry can be thought of as a reflection across itself that takes the isosceles triangle to itself. Every point of the triangle on one side of the line of symmetry has a corresponding point on the triangle on the other side of the line of symmetry, given by reflecting the point across the line. In particular, the line of symmetry is equidistant from all corresponding pairs of points. Another way of thinking about line symmetry is that a figure has line symmetry if there exists a line (or lines) such that the image of the figure when reflected over the line is itself.

Does every figure have a line of symmetry?

The required number of different distances possible is given as 36.

Given that,
In a board game, the distance a player travels is equal to the sum of the numbers shown when two 6-sided dice are tossed.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

Here,
1 dice have 6 outcomes
2 dice have 6 outcomes,
Number of possible combination = 6 × 6 = 36

Thus, the required number of different distances possible is given as 36.

Answer:

6 4/5

Step-by-step explanation:

He has 1 1/5 lb. He needs 8 lb.

He needs the difference between 8 lb and 1 1/5 lb, so this is a subtraction problem. We must subtract 8 lb - 1 1/5 lb.

8 - 1 1/5 =

We cna subtract the 1 from the 8, but we need a fraction with fifths at the 8 in order to subtract 1/5 from it. We borrow 1 from 8 leaving 7, and we write the 1 as the fraction 5/5. Now we have

= 7 5/5 - 1 1/5

We subtract 1 from 7 leaving 6, and we subtract 1/5 from 5/5 leaving 4/5.

= 6 4/5

The correct way of determining the distance between −56 and 44 is distance = |−56 − 44|

Distance is referring to the numerical measurement of how far an object is from a particular place.

Given that, what is correct way to determine the distance between -56 and 44,

So, the distance will be = |-56-44|

= |-100|

= 100

Hence the correct way of determining the distance between −56 and 44 is distance = |−56 − 44|

Answer:

Infinite solutions.

Step-by-step explanation:

The given equations are :

-5x + y = -2 .....(1)

20x-4y = 8 .....(2)

We have,

a₁ = -5, a₂ = 20, b₁ = 1, b₂ = -4, c₁ = -2 and c₂ = 8

[tex]\dfrac{a_1}{a_2}=\dfrac{-5}{20}=\dfrac{-1}{4}\\\\\dfrac{b_1}{b_2}=\dfrac{1}{-4}=\dfrac{-1}{4}\\\\\dfrac{c_1}{c_2}=\dfrac{-2}{8}=\dfrac{-1}{4}[/tex]

It means,

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex]

Answer:

x = 25

Step-by-step explanation:

Sun of the exterior angles of a quadrilateral = 360°

Therefore:

x + 40 + 6x + 2x + 20 + 3x = 360

Add like terms

x + 6x + 2x + 3x + 40 + 20 = 360

12x + 60 = 360

12x = 360 - 60

12x = 300

x = 300/12

x = 25
